Development of dynamic thermal input models for simulation of photovoltaic generators

Abstract

ABSTRACT Development of dynamic thermal input models for simulation of photovoltaic generators (PVG) is the main concern of this work. The dynamic thermal input models consist of insolation and temperature models. The model development involves acquisition of meteorological input data for Kampala at latitude (0.3476oN) and longitude (32.5825oE), measurement of physical conditions in which PVG is operating, carrying out thermal balance around PVG and application of solar analytic equations. The emerging models are simple simulated dynamic insolation and temperature models. These models were superimposed with quadruple sinusoidal waves to obtain superimposed simulated dynamic models. Furthermore, the superimposed insolation models were validated with the superimposed sky model and meteorological data while the corresponding temperature model was validated with the experimental data. The developed models become universal by substituting localised input parameters. Moreover, these models are useful for operation, installation, design and dynamic performance analysis of PVG.
